The strength of rock sample containing a few sets of discontinuities is first investigated. The results of models with simple geometries are compared with the available analytical solutions to verify the developed computer code, whereas models with complex geometries are simulated to better understand the fundamental behavior and failure mechanism of jointed rock mass. Furthermore, the stability of jointed rock mass in an underground excavation is studied, where rock failure process is determined by the 3-D NMM simulation. The simulation results provide valuable guidance on excavation process design and stabilization design in rock engineering practice.||URI:||https://hdl.handle.net/10356/102383
